Detailed Description

The following describes the embodiments of the present invention in further detail with reference to the accompanying drawings.

By figure 1 to 4 and give, axial sleeve 1 about including, the ascending standing groove 2 of opening has been seted up to the coaxial in the sleeve 1, coaxial logical groove 3 has been seted up on the 2 lower surfaces of standing groove, coaxial sliding connection has the upper end to stretch out the sampler barrel 4 of standing groove 2 in the standing groove 2, coaxial being equipped with can reciprocating in the sampler barrel 4 and closely laminating piston 5 rather than the inside wall, sampler barrel 4 lower extreme is equipped with rather than inside intercommunication and can insert the sampling tube 6 in leading to the groove 3, the sampling tube 6 lower extreme is the toper, the sleeve 1 left and right sides is seted up respectively about the axial and with the spout 7 that leads to groove 3 intercommunication, two spout 7 looks remote ends are coaxial respectively to be equipped with the slider 8 that can remove about, two sliders 8 all can contact with the lower extreme of sampling tube 6, two slider 8 lower extremes are respectively through connecting block 9.

In order to move the piston 5 up and down, the upper end of the sampling cylinder 4 is provided with a rotating handle 11 which can rotate back and forth, the upper end surface of the piston 5 is coaxially provided with a piston shaft 12, the upper end of the piston shaft 12 penetrates through the rotating handle 11, and the piston shaft 12 is in threaded connection with the rotating handle 11.

In order to enable the rotating handle 11 to swing back and forth, a T-shaped groove 13 with a downward opening is coaxially formed in the lower side of the rotating handle 11, and the upper end of the sampling tube 4 is connected with the T-shaped groove 13 in a sliding mode.

In order to fix the position of the sampling tube 4, the sampling tube 4 is sleeved with a limit sleeve 14 positioned between the rotating handle 11 and the sleeve 1, the front sides of the limit sleeves 14 are not connected, the right sides of the limit sleeves are hinged with a buckle 15 positioned at the front end of the limit sleeves, and the left side of the limit sleeve 14 is provided with a cylindrical block 16 which can be matched with the buckle 15.

In order to enable the sliding block 8 to move left and right, the opposite surfaces of the two sliding grooves 7 are respectively connected with the sliding block 8 on the corresponding side through a pressure spring 17.

In order to enable the connecting blocks 9 to move along with the sliding block 8, the lower end surface of the sleeve 1 is provided with a through groove 18 which is communicated with the sliding groove 7 in the left-right direction, and the two connecting blocks 9 are respectively connected with the through groove 18 in a sliding manner.

When the utility model is used, the buckle 15 is swung downwards to separate the buckle 15 from the cylindrical block 16, at the moment, the limit sleeve 14 is separated from the sampling tube 4, the device is placed on the skin of the affected part of a patient, the rotating handle 11 is pressed downwards, the rotating handle 11 drives the sampling tube 4 to move downwards, the sampling tube 4 drives the sampling tube 6 to move downwards, the sampling tube 6 is inserted into the through groove 3, meanwhile, the rotating handle 11 drives the piston shaft 12 to move downwards, and the piston shaft 12 drives the piston 5 to move downwards;

along with the downward movement of the sampling tube 6 along the through groove 3, the lower end surface of the sampling tube 6 is respectively contacted with the sliding blocks 8 at two sides, because the lower end surface of the sampling tube 6 is a conical surface, the lower end of the sampling tube 6 respectively pushes the two sliding blocks 8 to move back to back along the sliding grooves 7 at the corresponding sides and extrude the pressure springs 17 at the corresponding sides, the two sliding blocks 8 respectively drive the clamping jaws 10 at the corresponding sides to move back to back through the connecting blocks 9 at the corresponding sides, when the sliding blocks 8 are contacted with the outer edge surface of the sampling tube 6, the sliding blocks 8 stop moving to prop open or tension the skin of the affected part of the patient, and at the moment, the front end of the sampling tube 6 prick;
